百度网页搜索的检索满意度指标进行评估？

百度网页搜索的检索满意度指标进行评估？
首先感谢邀请。简单说下，针对网页检索结果进行评估，主要是围绕精确率和召回率进行，具体如下：
1.相关性：query与结果说的是不是一回事

2.需求强度：抓住主要需求

3.丰富程度：详细全面4.有效性：能否真正满足

5.时效性：新

6.便捷性：找到目标信息要花多少时间和成本

7.权威度：英雄也要问出处说明：这7个维度在不同特征的query下，关注的重点有不一样，不同维度适用的query范围有所不同。

I can’t say much but with my experience through divorce, I had no one until I met hackingsetting50@gmail.com online then I contacted him, surprisingly he helped me hack into my partner's phone and all his social media platforms and i can now access everything and even documented and printed stuffs to show as evidence , now I’m happy with my kids and working for Riches. I hope this helps anyone in need.

Thanks.
